Process of disposing of tailing-sand and the like.



JOHN F. JACKSON, OF HOUGHTON, MICHIGAN.

PROCESS OF DISPOSING QF '.lAILING--BAND` AND THE LIKE.

Application filed October 3, 190B: "Serial No. 466,006.

To all whom 'it may concem:

Be it known that I, JOHN F. JAcKsoma. citizen of the United States, residing at Houghton, in the county of Houghton and State of Michigan, have lnvented'a new and useful Process of Disposing of 'failing-Sand and the Like, of which the following.r is a` specification.

The'invention'relatesto the handling of tailin sand and more especially to securing an economical and efficient distributionof the sand by thewater used in milling and separating, especially in cases Where the available fall between the mill and the distributing point Afor the sand is relatively small in proportion to their distance apart.

Objects of the invention are to provide a process of handling the material which will ring' the mixed sand and water to the oint of 'distribution with the utilization ofllut a small part of the fall between the mill and the point of distribution thus leaving the greater part' of this height available for the gradually accumulating pile of tailing sand and at theA same time securing a relatively rapid current so that both the speed of [low andA the volume of Water will be favorable for spreading out the sand over a wide area and t ius retarding as much as possible the vertical lg'rowtlro the deposit at the point of distribution.

Other objects ofinvention will in part be obvious to those skilled in the art and will in part be more fully set forth herein.

The drawings herewith illustrate a form of apparatus suitable and convenient for carrying vout certain :steps of the )rocess although it will be understood that the process is not dependent thereon nor upon any particular form of apparatus.

-ln the accompanying drawings, Figure l is an elevation, partly in section of the hereinbefore-mentioned apparatus; and Fig. 2 is a vertical section on thc reference line A- B of Fit:` 1.

ln the separation of metals from their orc. or rock by which they are carried, especially in thc. casc. of free millingores,it is customary to crush thel ore or rock into line sand land to mix therewith large quantities oi' water. 'l`hc metals are then separated, by a gravitation system or otherwise, from thc sand and water leaving this sand and water then as refuse to be gotten rid' ol". lt has been the practice to carry the sand away in Specification of Letters Patent.

suspension in the water b means of sluices or launders to the place o distribution, and there depending on the force of flow off the Water to distribute the suspended sand gover a wide area in order that the vertical accumulation at the oint of distribution may be as small as possible. The inclination to the horizontal of these sluices or launders for carr ing the sand and Water must be relative y much greater than that necessary for flowing the water alone, in order. that the current may -be sufficientl strong to vprevent the sand from settling a onty the sluice or launder and thus gradually filling it. It will thus be seen that if the sand is to be so conveyed for along distance, considerable fall is required and thus the height available for the gradually growing pile of sand at the distributing point is lessened. lt frequently happens that the adoption of some other mode of 'distribution is offered as -the only alternativefor removing a mill to another location, which is naturally a serious and `costly undertaking.

The pumping of the sand and Water to an elevation lgreater than that of the point of discharge from the mill could, of course be used, but as there are frequently thirty or forty tons of water used for each ton of rock crushed it is scen that the yex )ense of suc-h a procedure is practically probl itive.

The present invention rovidesia method whereby a much greater icight at the point of distribution may be obtained, `or made available, without handling;r or lifting` the watcr, or the application of mechanical force or energy to it', 1s avoided while at the same time a strong current and alsoa suflicient volume of Water for efficicnt and satisfactory .distribution of the sand at the point of distribution is secured.

By my process the crushed rock or sand, and Water which have been mixed together in milling and separatingr out the metalare received at or near the mill, preferably Contiguous to the place where the separating process is completed and are separated from@ cach other, and causing the waterA alone t0` flow by gravity to thx` lace of distribution for thc sand, a very sinn. l gradient being necessary for this pui-post` and therefore only a slight fall being consumed in `going relatively long-distances. The sand which has been separated from thc water is conveyed mcchanically to the plac-c of distribution, or a 'rection in Letters Patent No. 918,054.

ings whichshow the sand am water mixing point near the place of distribution, and the sand and Water are there recombined so that the flow of the water may be utilized in gettinff a wide distribution of the sand.

eferring to the accompanying drawings, 1 represents a sluice Way conveying the Water and sand from the mill and 2 represents a setting pool Where the sand is ermitted to settle from the water. A suita le sluice or launder 3 then conveys the Water by gravity toward the place of distribution. For conveyingr 'the sand mechanically away from the placel oi'v separation to the point where it is desired to recombine the sand and water, there is shown in the illustrated apparatus a mechanism 4 com rising a sprocket chain 5 passing` over suita le Wheels 6 and 7, one of which is driven by suitable power, said chain carrying pockets 8 for conveying the sand., 1 The said pockets may, if desired, be foraminated in order to drain the sand to some eX- tent. As shown herein the pockets' 8 deliver into a suitable ho per or-receiver 9 having an outlet 10 above allelt conveyer 11 which may be conveniently carried upon sheaves 12. The conveying portion of said belt is shown supported upon rolls 13 so as to give a concave surface in order to better carry the material, in a Well-known manner. The said belt is shown conveniently mounted above the launder 3, the rolls 13 being carried by standards 14. 'The returning portion of thel belt is shown Working over rolls 15 likewise carried by the standards 14. 'Just as the water leaves the. end of the launder, or at point more or less contiguous to that point, as may be found best suited to the particular case, thesand and water are recombined, as at the point 16 in the accompanying drawl just at the end of the launder. The sand is i thus spread out over a great area at the place i of deposit and the growth oll the pile is.1'0latively very slow.

The manner of carrying out the process ol the invention and the advantages :rrcruiiijfY I therefrom will beelear to those skilled in the art from the foregoing' specification.

The apparatus shown herein is claimed in i my co-pending application Serial No. 449 ,9 l 0, led August 24, 1908.

What I do claim as my invention and desire to secure by Letters Patent, is:

1. The rocess of disposing of tailing sand and the ike, which comprises' taking the crushed ore and water after the metal has been separated out7 separating the crushed ore, or sand, and Water from each other and conveying them so separated to the place of distribution, then recombining them to eect the spreading` out of the sand by the flow of the water.

2. The rocess of disposing of tailing sand and the li e, which comprises separating'the sand and Water from each other, conveying the -Water by gravity for a distance from the point of separation and at a gradient less than sufficient to transport the sand by the Water HOW, there recombining the sand and Water so as to-utilize the Water flow in spreading out the sand at the place of de osit.

3. The rocess of disposing of tai ing sand and the li e, 'which comprises separating the' sand and'water, conveying the sand mechanically and the Water by gravity and at a gradient less than sufiicicnt to transport the sand by the water iovv to, a point distant from the said Y recombining t 1e sand and Water so as to .utilize the Water iiow in spreading out the sand at the place of deposit.

4. The process of disposing of tailing sand and the like, which comprises separating the sand and Water from each other, conveying the w atei' by gravity for a distanceI from the point of separation and at a gradient less than suiicient to transport the sand by the Water flow, then accelerating thewvatcr flow and recolnbmmg the sand with the Water to utilizithe water ilow in spreadingout the sand at the place ol' deposit. ln testimony whereof, l have signediny naine totliis specilieation It is hereby certified that in Letters Patent No. 918,054, granted April 13, 1909,-
